I would also say comma and semicolon. I learned about this last year. Why is it not the other two?
The hyphen is used for something like this, "short-term" that's an easy way to use an hyphen though.
A dash is somewhat like a hyphen. It's like a longer minus sign you could say.
"It was said by—Thomas Williams." (Random person I made up.)
Semicolon and comma would be the best answers, I believe. They bring together sentences.
